INDIANAPOLIS (AP) — An Indianapolis police report says the driver of a school bus that struck and killed a principal last month got out of the driver’s seat without putting on the parking brake.

The report says the students had boarded the bus and the driver was prepared to drive away when she got out of her seat. The report doesn’t say why the driver left her seat.

The bus rolled forward and fatally struck Amy Beverland Elementary School principal Susan Jordan. Two 10-year-olds were injured.

The report was available on the website www.buycrash.com . Indianapolis Metropolitan Police Lt. Richard Riddle said Monday that the department wasn’t releasing the report, but it had been forwarded to state police, which makes the information available to the website.
